Answer:
Sternocleidomastoid is the muscle which when when contracted unilaterally, will produce lateral bend of the spine
Explanation:
Sternocleidomastoid muscle is responsible for the turning of neck and its nodding. It consists of long muscles that are able to connect the three process of temporal bones i.e sternum, clavicle, and mastoid. Thus, this muscle can bend the spine laterally.
The medulla oblagonta. Its main function is to send signals to the muscles that control respiration to cause breathing to occur.
The answer is Negative charges on phosphate groups repel each other. The oxygen groups of a phosphoanhydride in ATP have electron cloud that repels each other. On hydrolysis, once a phosphate is lost, the electrostatic repulsion is reduced.
When ATP is hydrolyzed, it forms more hydrogen bonds with surrounding water molecules that when ATP is unhydrolyzed. Therefore, more energy is released since more bonds are formed than are broken. The net delta G is positive during hydrolysis of ATP.
The stronger survived and the weaker passed on... Those with a weaker immune system had trouble with sickness and usually ended up passing on but those with strong immune systems were stronger and healthier and lived.
